Opnext Releases First High Power IR Laser Device with Photo Monitor

The built-in monitor 637nm diode will enable system designers to optimize laser performance during environmental fluctuations which will be necessary for industrial and military applications.

Opnext, a global manufacturer of high power, low operating current red and infrared laser diodes, has introduced a 637nm, 120mW high power laser with a built-in monitor photo diode.

Opnext's HL63142DG red laser diode, which is designed for industrial and military applications, including military target acquisition, achieves optimal performance and output by enabling system designers to monitor the laser's performance and adjust output power in real time. Opnext customers are currently sampling the red laser diode for use in industrial and military applications.

Using a unique and proprietary design, the HL63142DG built-in monitor photo diode allows a system designer to control the optical performance by monitoring the photo diode current and adjusting for temperature and power variants. Performance monitoring capabilities are essential for maintaining constant laser output power in construction systems and biomedical and other applications that experience changes in their operating environments.

The HL63142DG operates at a temperature range up to 50°C and 120mW in the 637nm wavelength band in a 5.6mm diameter TO industry standard package.

"We expect to see initial demand for this high quality laser with built-in monitor photo diode to come from military target acquisition-type applications where precise laser control is an important performance parameter," said Tadayuki Kanno, President of Opnext's devices business unit. "The industry trend is moving toward producing laser diodes that are high power, while consuming less energy, and Opnext continues to innovate in bringing these key performance capabilities to market."

Opnext offers one of the industry's most comprehensive portfolios of laser diodes, spanning from 635nm to 850nm, driven by more than 30 years of innovative laser heritage. Opnext high quality, reliable red and infrared laser diodes are proven to consume a low operating current, which extends battery life, while still maintaining the integrity of the laser diode power in a variety of applications such as gun sights, rangefinders, line leveling construction systems and biomedical applications.

The HL63142DG is in mass production.

Opnext will demonstrate end application products that use the company's laser diode technology during the Photonics West conference, January 25-27, 2011, at the San Francisco - Moscone Center. The firm will be at Booth # 1837.

Formed out of Hitachi, Opnext supplies systems and OEMs worldwide with one of the industry's largest portfolios of 10G and higher next generation optical products and solutions. The Company's industry expertise, future-focused thinking and commitment to research and development combine in bringing to market the most advanced technology to the communications, defense, security and biomedical industries.
